A new form of technology called HVAC is something you may have heard of which the meaning is heating, ventilation and air conditioning. It is electricity that would be depended on with this new technology. Advancements in science like the fields of thermodynamics, fluid mechanics and heat transfer, are what this new technology rely on.


Be informed that HVAC technology is among the branches of mechanical engineering that is included. It is the main role of HVAC system at to control the air temperature in large offices and production areas, thus there is a provision of a comfortable working condition that would lead to an increase in the productivity of the employees.


Nowadays, skyscrapers, offices and big factories are growing in number that would lead to a need to control the air temperature, and with the installation of HVAC system at, this objective can be reached.


It is interesting to know that the ancient Romans started the practice of heating the air temperature of their environment by installing heated airducts in their structures. The discover of thermodynamics had led to the invention of refrigeration that also led the way to the innovation of air conditioning. In order to attain the cool air, the concept of thermodynamics is applied which is the process of removing the heat.


There is an accomplished air conditioning process happening when the heat is removed through the refrigeration cycle.


In order for a home to have the central heating and air conditioning system functional, air ducts have to be installed since these will be used to force the cool or hot air into the designated areas of the house.  In the very cold months of winter, the central heating system is very useful. Note that a central heating system can be fuelled with the use of oil, electricity, gas or solar power. Generally, the primary heating appliance is placed in the basement.  The delivery of the heat is through the air ducts, while the steam is coursed through the pipes and room radiators. A good level of heat in an area can be maintained by having a good insulation installed that will prevent the heat from escaping.



On the other hand, when temperatures go up during summer season, people would use air conditioners to keep themselves comfortable with a cool environment. The heat is removed from the atmosphere through the air conditioners being ran through electricity and thus making the environment cool. It is advisable that you get an air conditioner that can provide cool air during summer and can keep you warm during the cold winter months.
